No
The device description details a simple pulsed shortwave diathermy device with manual settings and no mention of adaptive or learning capabilities. The performance studies focus on physical output measurements, not algorithmic performance.
Yes
The device is indicated for the palliative treatment of postoperative edema and pain, which are therapeutic applications.
No
The device is indicated for adjunctive use in the palliative treatment of postoperative edema and pain, which are therapeutic rather than diagnostic purposes. It is a pulsed shortwave diathermy device, used for treatment, not diagnosis.
No
The device description clearly outlines hardware components including a Generating Unit, Treatment Applicator, cable, and power cord, indicating it is a physical medical device, not software-only.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for the "palliative treatment of postoperative edema and pain in superficial soft tissue." This is a therapeutic use, not a diagnostic one.
- Device Description: The device is a "pulsed shortwave diathermy device" that applies energy to the body. This is consistent with a therapeutic device, not one used to examine samples outside the body.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.) or providing information about a patient's health status based on such analysis.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or screening purposes. This device does not fit that description.

Device Description
The Model PMT850 device is a pulsed shortwave diathermy device. The Model PMT850 system consists of a Generating Unit connected by a cable to the Treatment Applicator. The Treatment Applicator and cable are a single unit which is connected or disconnected easily from the Generating Unit. The Generating Unit connects to a standard AC electrical outlet by a grounded 3-prong UL/CSA approved, medically rated electric cord.
Treatment with the Model PMT850 requires placing the Treatment Applicator on top of any standard dressing over the area to be treated, setting the dials on the Generating Unit, and turning the device on. There are 6 possible pulse frequency and 6 possible power control settings on the generating unit of the Model PMT850, providing 36 setting options for treatment. Suggested treatment settings are discussed in the Operating Manual for the Model PMT850.

The Treatment Applicator and cable are a single unit which is connected or disconnected easily from the Generating Unit. The Generating Unit connects to a standard AC electrical outlet by a grounded 3-prong UL/CSA approved, medically rated electric cord.
Treatment with the Model PMT850 requires placing the Treatment Applicator on top of any standard dressing over the area to be treated, setting the dials on the Generating Unit, and turning the device on. There are 6 possible pulse frequency and 6 possible power control settings on the generating unit of the Model PMT850, providing 36 setting options for treatment. Suggested treatment settings are discussed in the Operating Manual for the Model PMT850.
INTENDED USE ்.
The Model PMT850 is indicated for adjunctive use in the palliative treatment of postoperative edema and pain in superficial soft tissue.

SUBSTANTIAL EQUIVALENCE SUMMARY D.
The Model PMT850 has the same intended use and indications for use statement as the predicate device. The Model PMT850 has the same technological characteristics as the predicate device, with the exception of the lower power required from the Generating Unit to provide an equivalent amount of Peak Power from the Treatment Applicator, which does not affect safety or effectiveness. In addition to a side-by-side comparison of the descriptive characteristics of the Model PMT850 and the predicate presented below, performance studies were conducted to ensure equivalent performance compared with the predicate: Applicator Field Measurements, and Output Energy Comparison. The decision algorithm brings us to a determination of device substantial equivalence with the predicate.
TECHNOLOGICAL CHARACTERISTICS ប៉
The general technological characteristics of the Model PMT850 and the predicate are equivalent. This includes: power supply, operating principle, energy transfer mechanism, treatment applicator, device physical conformation (weight and size), and packaging.
The following technical specifications are also found equivalent between the Model PMT850 and the predicate: power required, fuse protection, operating frequency, RF Output Impedance, RF Pulse Width, RF Pulse waveform, pulse frequency, pulse duty cycle, pulse control accuracy, peak RF applicator power, average RF applicator output power, exposure timer, and timer accuracy (see Table 1 below). The only technical specification that differs is the lower peak RF generator power required for the Model PMT850 Generating Unit to provide an equivalent amount of Peak Power as the predicate from the Treatment Applicator for each of the six power settings.

г. TESTING
Substantial Equivalence
Applicator Field Measurements and Output Energy Comparison testing was conducted by two independent laboratories to determine equivalence in device performance of the Model PMT850 and the predicate device. The results of these tests support the substantial equivalence of the Model PMT850 with the predicate device.
Conformance to Standards
Prior to marketing, the Model PMT850 will comply with all standard requirements listed by an NRTL and also will conform to electrical safety (UL 60601-1), electromagnetic compatibility (IEC 60601-1-2) and packaging guidelines (ASTM D4169-05).
Biocompatibility testing was determined not to be required because the device does not contact patient skin. However, it should be noted that the treatment applicator covering is made of a high-grade polyethylene foam, which has passed biocompatibility tests for cytotoxicity/irritancy (ISO 10993-5).
CONCLUSIONS G.
ProMedTek, Inc. has demonstrated through the comparison of characteristics and comparison of performance testing, that the Model PMT850 is substantially equivalent to the predicate, MRT sofPulse shortwave diathermy device.
